PORTABLE BOOK-SUPPORT.

SEECIFICA'IION formingpart of Letters Patent No. 677 ,7 31, dated July2, 1901.

Application filed April 15,1901.

To 510% whom it may concern-.-

Be it known that 1, WILLIAM P. ALLRED, a citizen of the United States,residing at Corydon, in the county of \Vayne and State of Iowa, haveinvented a new and useful Portable Book-Support, of which the followingis a specification.

My object is to facilitate the labor of making records in a book bymeans of pen and ink.

Heretofore various forms of book-supports have been provided forretaining books in inor examining records; but in no instance has aself-adjusting book-support been provided that will automatically raiseand lower and level the pages of a book at any point where the book isopened, as contemplated by my invention.

My book holder and leveler is composed of a portable base, a crank-shaftand rollers, and an adjustable hand or arm rest, as hereand illustratedin the accompanying drawings, in which- Figure 1 is a perspective viewof the complete device ready for supporting and leveling an open book asrequired to retain the open pages in a convenient position for a personto write thereon. Fig. 2 is a perspective view of a detachable arm-restin an inverted position. Fig. 3 shows the rear side of the book-supportand the elevated end of an open record-book supported thereon advantageously for the purpose of making records on the open pages or examiningthe contents previously entered.

The base of the book-support is preferably a skeleton frame ofquadrangular form twenty-four inches long and eighteen inches wide andspecially adapted for use in countyrecorders offices. It is obvious,however, that it may be a solid base and vary in size as desired to suitbooks of dilferent sizes.

The letters A and A designate the straight wooden end bars of the frame,and B and 13 two mating bars in parallel position at the central portionof the frame. These four bars are rigidly connected by mortises andtenons or in any suitable Way, with a side bar 0 at their rear ends thatis uniform in thickness therewith. The other side bar or front bar D isset on edge and fixed to the ends of Serial No. 55,928. (No model.)

the bars A, A B, and B so that its top edge will be elevated about oneinch from the top of the frame.

Shaft-bearers H are fixed on the tops and rear end portions of the barsA, A B, and B and in alinement with each other to support a rock-shaftJ,mounted on said bearings. The cranks J and J of the shaft project inreverse ways from the axis of the shaft and are extended in length tocorrespond with the length of the rollers K and K mounted thereon. Adetachable arm-support,consisting of a flat board M, provided with fixedtriangular-shaped brackets N and fixed dowelpins 1' on its under side,is adapted to be detachably fastened to the front side bar D by simplyinserting the dowel-pins in perforations r in said bar, so that thearm-support can be readily shifted relative to the side of the book onthe support upon which a record is to be made or examined while the bookis open. The ends of the rollers are designed to alternately engage thetop surfaces of the parallel bars of the base above which they rotatewhenever one side of a book on the rollers is lowered to its downwardlimit and the other side is elevated.

It is obvious the rollers can be dispensed with, so that a book can besupported and leveled while resting upon the cranks J and J 2 direct, orin place of rollers extending the entire lengths of the cranks shortrollers or disks may be mounted at each end of each book is opened toany page desired to be examined or to be held in a favorable positionfor writing thereon.

Having thus described the purpose, construction, and operation of myinvention, its practical utility will be readily understood by personsfamiliar with the art to which it pertains, and what I claim as new, anddesire to secure by Letters Patent therefor, is-- 1. In a book supportand leveler, a base, a rock-shaft having cranks projected in reverseways from its axis mounted upon bearers, bearers fixed to a base, tooperate in the manner set forth for the purposes stated.

2. Abook-supportandbook-leveler consisting of a base having a fixed barprojecting above its front edge to engage the end of a book, bearersfixed to the rear edge portion of the base to support a rock-shafthaving cranks that extend in reverse Ways from the axis of the shaft androllers on the cranks, arranged and combined to operate in the mannerset forth for the purposes stated. 7

3. A book support and leveler comprising a portable base, a bar fixed ontop of the front edge of the base'to engage the end of a book, bearersfixed in alinement With each other on top of the rear edge portion ofthe base to support a rook-shaft, a rock-shaft having two cranksprojecting in reverse Ways from the axis of the shaft and rollers on thecranks and the shaft mounted on said bearers and an arm-rest attached tothe front edge of the base, arranged and combined to operate in themanner set forth for the purposes stated.
